This is an easy question but I can't find good documentation.

After installing or "sourcing" biocLite and installed relevant packages (edgeR, etc) I can run my analyses. But after closing the R session, and then restarting it, I have to resource BiocLite and then load all packages again. Seems like I wouldnt want to do this each time. Is there an appropriate way to have my packages saved from previous installations, so i can just load (e.g. > library(xxx) ) all neccessary BiocLite packages ?

Thanks

Sorry, I didn't explain myself well. I haven't been using Bioconductor for long, so thought I had missed something in how packages were loaded/retained/accessed. Anyway I figured out my brainfart. I was switching between 2 servers and R versions and had not installed BiocLite on both. So I thought I had installed the edgeR package on my local server, but had not so obv. it wouldn't load! Thanks for the reply and sorry for the question.

I think you misunderstand the process. Once you have installed a package, it is available on a permanent basis. In other words, you should be able to just start R and then use library(edgeR), without having to reinstall the package.
